danny has a trianglular pyramid all triangles are conguent what is the surface area?the height is 6in and the width is 5in

Gre4nikov [31]

Answer: The answer is 60 square inches.

Step-by-step explanation: Given that Danny has a triangular pyramid where all the four triangles are congruent. The height and base of one triangle are 6 inches and 5 inches respectively. We are to find the surface area of the pyramid.

The area of one triangle is given by

$A=\dfrac{1}{2}\times\textup{base}\times\textup{height}=\dfrac{1}{2}\times 5\times 6=15~\textup{sq. inches}.$

Since the pyramid consists of four congruent triangles, so the surface area of the pyramid will be

$S=4\times A=4\times 15=60~\textup{sq. inches}.$

Thus, the answer is 60 sq. inches.
